Accepted Answer

A)  southwestern 
B)  southeastern 
C)  northeastern 
D)  northwestern 
A)  southwestern 
B)  southeastern 
C)  northeastern 
D)  northwestern B

Question 2

Why is it not a good idea to seek shelter from a thunderstorm beneath a tree?

Accepted Answer

A positive charge tends to concentrate in upward projecting objects, and the upward return stroke that meets the stepped leader is most likely to originate in such objects. Therefore, it is not a good idea to seek shelter beneath a tree during a thunderstorm because many lightning fatalities have occurred in the vicinity of trees.
